JPRGCIESS 01F WATERPRFING TILE AND THE LIKE.

Application filed September 13, 1920. Serial No. 411,131.

T 0 all we kom it may concern Be it known that T, JAMES T. PoKoRNY, a citizen of the United States, residing at Cedar Bayou, in the county of Harris and State of Texas, have invented certain new and useful Improvement in a Process of Waterproofing Tile and the like, of which the following is a specification. 1

This invention relates to a novel process of water proofing tile and the like.

The object of the herein described process of treating tile, brick and the like is to make the same proof against water so that they will not absorb any considerable amount of moisture.

With the above and other objects in view the invention has particular relation to a novel process hereinafter described and which iscarried out in the manner stated. The process is carried out through the instrumentality of a kiln which is shown in the accompanying drawing, said drawing illustrating a transverse sectional View; of the kiln.

In the drawing the numeral 1 refers to the furnace wherein the tile, or brick are arranged so that the heat will circulate through between them. In front of the furnace there is a fire chamber 2 which is sep arated from the furnace by a transverse partition wall 3. The numeral 4: designates the burner which may be of any conventional form. The numeral 5 designates a smoke j within the furnace whereby said products stack which is connected with the furnace through the flue 6 and this flue may be oompletely closed by means of the damper 7.' In the top of the furnace there are a number bf funnels 8 through which coal tar may be. pour d into the furnace, and suspended above the respective funnels are the closure plugs '9. These means of suitable cables 10, which are attached thereto at one end and operate over plugs are suspended by' suitable pulleys and whose other ends carry the counter weights 11.

The process is carried out as follows:- The tile are arranged in the furnace and are burned in the usual way, the suction through the flue 6 drawing the flame and heat through the spaces between the tile so that said tile are thoroughly burned. After the tile are burned sufficiently the fire is extinguished, and while the furnace and tile are still hot, a quantity of coal tar is poured into the funnels 8 and said funnels are then closed by the plugs 9 and the damper is closed so as to cut ofi all openings from the furnace and exclude all moisture. The heat Within the furnace will of course keep the tile and air in the furnace dry and hot. The dry hot air will convert the coal tar into smoke and vapor which will completely cover the tile and be absorbed into the pores thereof. As the tile gradually cools these products of coal tar which have cove-red the same will be further absorbed, completely filling the pores of the tile and rendering the same water proof.

. What I claim) is p The process of water proofing tile and the like, consisting of placing said tile in a furnace then burning the same, then pouring coal tar into said furnace while the furnace is hot and closing all the openings of said furnace to exclude moisture and to confine the vaporized products of the heated coal tar JAMES T. POKURNY.
